Discussion on Drilling Construction Method for a Contract Section of Deep Prospecting Project in Xiaoqinling
Abstract:Discussion is made on drilling construction of borehole wall protection & leakage control, borehole structure, accident prevention and treatment method in the deep prospecting project in Xiaoqinling, especially the application breakthrough of washing fluid with strong wall protection performance and multilevel casing technology basically resolved construction difficulties in thick overburden with buried depth of 600～800m in quaternary and tertiary with fault gouge.
